Lub quarter kawg, ib qho ntawm pebkhoom siv kho mobcov neeg tau tuaj rau peb tom qab peb ua tsis tau raws li qhov kev sib tw nrog lwm tus neeg muag khoom. Tus qauv tsim tshwj xeeb tau teev cov phab ntsa ntsug, thiab txhua qhov kev sim tau xaus nrog cov khoom daig hauv pwm lossis khawb qhov chaw uas tsis tau kuaj xyuas. Peb ntxiv 0.75℃ntawm taper rau qhov chaw tseem ceeb, kho cov txheej txheem cua txias, thiab thawj qhov kev tsim tawm tau tshem tawm QC nrog tus nqi tsis lees paub hauv qab 2%. Cov neeg feem coob saib ntawm qhov ua tiav yuav tsis pom qhov taper. Pab neeg accounting yeej pom qhov sib txawv ntawm cov nqi rov ua haujlwm.
Draft lub kaum sab xis nyob rau hauv kev txhaj tshuaj molding yog lub me me taper siv rau ntsug nto ces qhov chaw tso tawm huv si los ntawm cov pwm. Lub hauv paus pom zoo yog 1.5℃txog 2℃rau qhov tob txog li ob ntiv tes. Koj yuav pom tus lej ntawd hauv txhua phau ntawv qhia tsim. Qhov koj yuav tsis pom yog kev piav qhia vim li cas nws tsis ua haujlwm thaum lub sijhawm koj qhia cov khoom siv zoo nkauj, siab -cov ntaub ntawv shrinkage, lossis cov cua txias uas tsis tau tsim nrog kev tawm hauv siab.
Tus Nqi Mechanics Feem ntau RFQs Npe
Shrinkage yog qhov teeb meem tseem ceeb. Thaum cov yas molten txias hauv ib kab noj hniav, nws cog lus rau lub hauv paus. Polypropylene shrinks 4-5%; iav-filled nylon coj txawv txawv;PEBnqa nws cov teeb meem nrog siab nruj. Qhov no shrinkage tsim kev sib txhuam uas resists ejection. Yog tsis muaj cov qauv tsim nyog, ejection quab yuam spikes, thiab lub zog ntawd tshwm sim nyob rau hauv koj lub sij hawm voj voog, koj seem seem, thiab koj lub sij hawm tu pwm.
Kev tsim qauv tsim nyog tuaj yeem txo qis ejection quab yuam mus txog 60%. Qhov kev txuag tiag tiag los ntawm qhov uas txo qhov ua rau: nrawm dua, tsawg dua ejector pins sib tw rau cov tub ntxhais ntim nrog cov cua txias, thiab ncua sij hawm ntev ntawm pwm polishing. Ntawm qhov ntim siab tshaj 50,000 units ib xyoos ib zaug, txawm tias tsib -thib ob lub voj voog txo qis rau hauv kev txuag nqi tseem ceeb. Tab sis tsuas yog hais tias lub kaum sab xis ntawm lub kaum sab xis thiab qhov cua txias yog tsim ua ke. Peb tau pom cov neeg siv khoom poob feem ntau ntawm qhov muaj peev xwm los ntawm kev ua kom zoo ib yam tsis muaj lwm qhov.
Ibsensor vaj tsevhauv PEEK tau khiav 18% tsis lees paub nrog 0.8℃cua ntsawj ntshab. Cov khoom tawv tawv ua rau ejection nyuaj, thiab cov pwm xav tau kev npaj polishing ntawm 35,000 cycles. Tom qab nce cov cua ntsawj ntshab mus rau 1.2℃thiab kho lub sijhawm ejector, kev tsis lees paub poob qis dua 3%, thiab cov pwm khiav dhau 120,000 lub voj voog ua ntej nws thawj zaug tau teem tseg. Tus nqi ib feem ntawm kev txhim kho ib feem ntawm qhov kev tsim kho thib ob.
Qhov twg Phau Ntawv Teev Npe Tsis Ua Haujlwm
Txoj cai "1℃per inch" tau rov ua dua kom txog thaum nws ua haujlwm raws li txoj cai kev lag luam. Nws tseem nco cov kev hloov pauv tseem ceeb uas yuav ua rau koj them nyiaj yog tias koj tsis ntes lawv thaum ntxov.
Textured nto tsim micro-undercuts uas ua zoo li me me thauj tog rau nkoj tuav qhov chaw. Peb tus qauv yog 1.5℃ntxiv cov qauv ntawm 0.001 nti ntawm qhov tob ntawm kev ntxhib los mos. Lub teeb PM-T1 kev ntxhib los mos xav tau 3℃yam tsawg kawg nkaus; hnyav textures tuaj yeem thov 5℃lossis ntau dua. Ntawm no yog cov lus qhia feem ntau hla: qhov kev ntxhib los mos qhov tob koj tus kws tsim qauv tau teev tseg thiab qhov kev ntxhib los mos qhov tob tiag tiag txiav rau hauv cov pwm hlau tsis tshua sib haum raws nraim. Peb ntsuas qhov kev ntxhib los mos qhov tob ntawm txhua lub cuab yeej ua ntej thawj tsab xov xwm vim tias qhov sib txawv ntawm 0.0005 tuaj yeem txhais tau tias qhov sib txawv ntawm qhov ejection huv si thiab rub cov qhab nia hla koj qhov kev khiav tag nrho.
iav- cov yas ntim puv yog abrasive thiab hnav cov pwm nto sai dua, feem ntau xav tau 2-3℃cua ntsawj ntshab. Tus kheej-cov ntaub ntawv lubricating zoo li nylon tuaj yeem ua haujlwm nrog zero cua ntsawj ntshab. Peb tseem pom zoo 0.5-1℃rau kev tsim khoom sib xws. Nyob rau hauv tus qauv khiav, lo ib zaug lossis ob zaug muab cov ntaub ntawv tseem ceeb rau koj. Hauv 50,000-unit txhua hli ntau lawm, tib lo lo ua ib txoj kab nres thiab sib tham nrog koj cov neeg siv khoom txog kev xa khoom qeeb.
Yam koj tau txais ua ntej cog lus rau Tooling
Feem ntau RFQs peb tau txais muaj cov duab kos duab qhia los ntawm pab pawg tsim khoom, tsis tau lees paub qhov tseeb ntawm cov pwm pwm. Cov kab ke ntawd ua rau muaj feem tseem ceeb ntawm cov cuab yeej siv rov ua haujlwm dua.
Peb DFM tshuaj xyuas chij cov ntawv sau- cuam tshuam txog kev pheej hmoo ua ntej cov cuab yeej quotes tiav. Qhov koj tau txais yog qhov cim -up version ntawm koj cov duab geometry nrog cov qauv tsim tshwj xeeb uas tau sau tseg ntawm txhua qhov chaw tseem ceeb, hla- hais tawm tsam koj cov ntaub ntawv shrinkage profile thiab koj cov lej kev ntxhib los mos (SPI, VDI, lossis Pwm-Tech). Qhov no tsis yog daim ntawv teev npe dav dav. Nws yog ib daim ntawv uas koj tuaj yeem xa ncaj qha rau koj pab pawg engineering uas qhia meej qhov twg koj tus qauv tsim tam sim no yuav ua rau muaj teeb meem ejection thiab lub kaum sab xis daws txhua qhov.
Rau siab -cov ntaub ntawv shrinkage zoo li PP, peb ua qauv ejection force profile siv Mould Flow simulation thiab txheeb xyuas qhov twg cov qauv qauv yuav tsis txaus. Rau qhov uas yuav tsum tau nyob ze -zero draft, peb soj ntsuam lwm txoj kev ua ntej:collapsible coresnrog cov ntaub ntawv meej meej ntawm cov neeg pov thawj cov cim lawv tawm, xaiv cov khoom siv hloov pauv, lossis tom qab-moulding. Txhua txoj hauv kev muaj tus nqi thiab ncua sij hawm cuam tshuam zoo dua los tham txog ntawm theem nqe lus tshaj li pom thaum thawj tsab xov xwm.
Kev sim yooj yim rau koj qhov kev sib raug zoo ntawm tus neeg muag khoom tam sim no: yog tias koj xa cov ntaub ntawv CAD thiab tau txais tus nqi yam tsis muaj daim ntawv tshaj tawm DFM, cov teeb meem ntawm lub kaum sab xis yuav tshwm sim ntawm thawj tsab xov xwm tshuaj xyuas. Thaum ntawd, koj tau cog lus rau ib lub cuab yeej uas yuav xav tau kev hloov kho lossis hloov.
Thaum Zero Draft tshwm sim hauv koj qhov kev xav tau
Cov pab pawg engineering qee zaum thovxoom daim duabrau qhov laj thawj ua haujlwm. Cov kev thov no tsis yog qhov tsis tsim nyog, tab sis lawv xav tau kev tshuaj xyuas dhau ntawm kev txheeb xyuas lub thawv ua tau.
Ib qho xoom-draft lub tog raj kheej nrog O- nplhaib foob ntsib qhov teeb meem tseem ceeb: cov qauv tsim nyog rau kev tshem tawm huv tuaj yeem cuam tshuam lub foob foob. Peb tau ua haujlwm ntawm daim ntawv thov PP lub tog raj kheej qhov twg txawm tias 0.2℃yuav tiv thaiv O-ntiv nplhaib los ntawm kev zaum kom zoo. Cov kev daws teeb meem yuav tsum tau hloov cov khoom siv thiab tshwj xeeb ejection lub sij hawm, ho complex dua standard tooling tab sis ua tau zoo nrog rau kev npaj ua ntej.
Thaum tus neeg muag khoom pom zoo rau xoom tsab ntawv yam tsis tau nthuav tawm lwm txoj hauv kev, lawv tsuas yog ncua qhov teeb meem rau hauv pem teb ntau lawm. Peb muab cov kev sib pauv hauv kev sau ntawv ntawm cov lus hais: cov cuab yeej siv tus nqi sib txawv ntawm xoom daim ntawv thiab 0.5℃feem ntau yog 40-70%, thiab peb qhia koj raws nraim qhov twg tus nqi los ntawm. Koj txiav txim siab nrog cov lej nyob rau hauv pem hauv ntej ntawm koj.
Rau cov pab pawg ua haujlwm ntawm textured -surface project, high-cov ntaub ntawv shrinkage, los yog qauv- rau - kev hloov pauv, upload koj cov ntaub ntawv CAD thiab peb yuav rov qab DFM tawm tswv yim nyob rau hauv 24 teev qhia raws nraim qhov twg koj cov kaum sab xis sawv ntsug.
